OIL BURNER.

Application filed March 21, 1923.

drawings, and to the characters of reference marked thereon, which form a part of this application. 1

This invention relates to improvements in oil burners, and particularly to a type adapted to burn light fuels, such as stove distillate, kerosene, gasoline, etc, and is especially intended to be used in hot air furnaces and other heating plants, and with low-pressure steam boilers.

The principal objects of my invention are to provide a burner of this type which may be used with either natural or forced draft, and with the latter draft will develop many times its normal heat in a very short space of time; one with which a check-draft may be used, in connection with either natural or forced draft; one in which no carbon will form in the fuel or vaporizing chamber; one in which a fire of equal intensity is formed all around the vaporizing chamberwhile the supply pipe is out of the direct line of heat; one in which the flow of fuel may be regulated to give the right mixture regardless of the kind of draft; one which is extremely economical in its fuel consumption, and one which may be installed in any furnace, and any part, if necessary, can be easily removed and inspected without taking out any lengths of piping, etc.

The burner is also very simple in construction having few parts, and is compact, and inexpensive to manufacture, and will last a long time without replacement of any parts.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views.

Fig. 1 is a side elevation of the burner.

Fig. 2 is a sectional elevation of the same.

Referring now more particularly to the characters of reference on the drawings, the

Serial No. 626,560.

numeral 1 denotes a hollow bell-shaped body, the lower flange 2 of which is adapted to rest on any furnace grate. Drilled radially through the upper portion of the body all around the same are equally spaced horizontal holes 8, in two or more vertical rows, depending on the size of the burner, the upper row having the largest holes, which are drilled as close to the top face or wall a of the body as possible, said wall being substantially flat, and having a shoulder 5 set in a certain distance from the outer periphery of the body.

A. fuel supply pipe 6 is screwed into the wall 4:: centrally thereof, and discharges onto the top of the same.

Removably and closely seated on top of the body 1 outside the shoulder 5 and centrally located thereby is an inverted cup 7, provided with a plurality of vertical and radial slits 8 cut upwardly a certain distance from the lower edge thereof, and at intervals all around the same, the slits being located centrally above certain of the upper holes 3.

The space enclosed between the cup and body wall l forms the fuel or vaporizing chamber 9 and theoretically the cup could be formed as one with the body, but for obvious reasons it is made as a separate member, being removable when cleaning outis necessary, and being more easily and cheaply manufactured.

In operation, fuel is allowed to flow into the chamber 9, and is initially heated to the vaporizing point by any suitable means, such as by the application of a blow torch, waste paper, or other material, to the body and cup.

The vaporized fuel can only escape through the slits 8, and is ignited by con tact with the burning initial heating means. The ignited jets of fuel are immediately mixed with the air passing up inside the body and out through the horizontal holes 3, the amount of fuel allowed to pass into the chamber being regulated according to the amount of air or draft available or being used.

It will thus be evident that the fire thus had is of equal intensity all around the body, and that it will be directly away from the vaporizing chamber, while at the same time suiiicient heat is of course thrown against the cup to keep the fuel flowing therein vaporized.

' tie-ups With various other burners, is eliminetted, as I have found from tests covering several days of continuousperformance.

The design of the burner is such that forced draft may be used therewith, the fuel chamber, in spite of the greater volume and intensity of the fire, being maintained in its cool condition, since agreater volumeof the cold incoming airis being directed against the bottom of the chamber to counteract the effect of the greater heat being transmitted thereto;

A check draft, such as causes a good many oil= burners to function very unsatisfactorily, may also be used With my burner Without any trouble.

Nothing but" air passes through the holes 3, and it will be seen that should the slits 8 everbecome-choked up, the cup 7 may be instantly removed for cleaning Without disturbing any other member.

From the foregoing description it will be readily seenthat' l have produced such a device as'substantially fulfills the objects of the invention asset forthherein.-

While this specification sets forthin detail the present and preferred construction of the device, still in practice such deviations through thesid'es of the chamber above and in substantially the same vertical plane assaid air passages.

2. An oil burner comprising a hollow body open on its lower end and covered on its upper end, a fuel pipe leading up inside thebody and" connected thereto to dis charge on top of the body, horizontal orifices through the body-Wall just under the top Wall thereof, an-d a'ninvertedeup reinovablyseated on top ofthe body and forming" an enclosed chamber therewith, said cup'having a plurality of radial slits in its-side-ex tendingupwardly from the lower edge thereof, the outer ends of theslit's and air passages lying in a substantially commonvertical plane.

An oil burner comprising a one pieee body forined as an inverted cup terminating at its lower end in an outwardly flaring and substantially horizontal fian'ge,- a removable inverted cup having a snug fit ontop of thebody and forming an enclosedi chamber therewith, and l'iorizon'tally disposed. and spaced passage means through the body-cup and chamber-cup walls.

In testimony whereof I afiixmy: signature;
